Title: Release paper and its production
Inventor: IWAMOTO KIYOSHI
IPC: D21H27/00
Filed: 1991-02-08
Abstract: PURPOSE:To provide a release paper having a new construction to decrease the coating amount of the releasing agent which is a problem of conventional release paper, to solve the problem of the deterioration of the appearance with time caused by the irregular surface of the paper substrate and to provide a process for producing the above release paper. CONSTITUTION:The objective release paper is produced by successively laminating a pigment layer, a resin layer and a releasing layer on at lease one surface of a substrate, wherein the surface flatness of the resin layer is >=1,000sec/10cc. A characteristic feature of the paper is the application of the resin layer in such a manner as to get the surface flatness of >=1,000sec/10cc. The paper having the above construction has excellent effects for getting (1) sufficiently high releasability with a small amount of a releasing agent, owing to the suppressed impregnation of the releasing agent into the supporting substrate, and (2) high adhesivity between the releasing layer and the tacky adhesive to prevent the deterioration of the appearance of the tacky adhesive product over a long period.

Filed: 1989-02-17
Abstract: PURPOSE: To secure stability in adjustment and definiteness in characteristic of materials by measuring a force imparted in the length direction of a workpiece and adjusting a welding voltage applicable to this workpiece in accordance with the measured force. CONSTITUTION: A chain link 1 placed on a saddle 2 is held between two pressing steel pieces 3 and applied with a welding voltage through electrodes 4.

Title: Felt clutch mechanism
Inventor: WATANABE TAKASHI
IPC: G11B15/44
Filed: 1990-02-21
Abstract: PURPOSE:To eliminate torque stick and torque variation, and to supply stable torque by forming the groove part of the abutting surface of a revolving member abutted on a felt member into the form of a wave. CONSTITUTION:When driving force is transmitted to the input gear 3a of a first clutch member 3, power is transmitted to a second clutch member 6 through the felt member 5 by friction transmission between the felt member 6 and the groove part 6b of the second clutch member 6. At this time, a friction coefficient between the felt member 5 and the groove part 6b is changed from static friction mua to dynamic friction mub, but the surface of the groove part 6b is formed previously into a curve exhibiting a gently-sloping wave form. Therefore, the variation of the friction coefficient is reduced, and difference between the static friction mua and the dynamic friction mub is reduced. Accordingly, a torque characteristic becomes uniform as well. Thus, the torque stick and the torque variation are eliminated, and the stable torque can be supplied.

Abstract: PURPOSE:To reduce the tape drive torque and to prevent damage to a tape by adopting the constitution that the tape winding quantity to a winding side tape guide is made smaller than the tape winding quantity to the supply tape guide in the tape loading state. CONSTITUTION:The 2nd support block 4 is pressed into contact onto the 2nd lock block 15 before the end of sliding of a rack plate at loading to position guides 4a, 4b. On the other hand, the 1st support block 3 is abutted onto the 1st locking block 14 before the end of turning of a loading disk 5 to position the guides 3a, 3b. Thus, the tape is drawn out of the cassette at the end of loading, guided by a tape unloading pin 9a, a fixed head 17 and the 1st upright guide 3a and the tape tilt angle is changed by the 1st tilt guide 3b. The tilt angle is corrected by the 2nd tilt guide 4b for the tape led out of the guide cylinder 1 and guided by the 2nd upright guide 4a, a head 18, a pinch roller 19 and a capstan 20 or the like. Thus, the tape torque is reduced and the damage of tape is prevented.

Title: Manufacture of macromolecular actuator
Inventor: AZUMI KINSHI
IPC: B25J7/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To obtain a macromolecular actuator element whose displacement is large, by causing an ion exchange resin formation to adsorb a metal complex in an aqueous solution and reducing it, performing cleaning after depositing metal on the surface, and forming a metal electrode. SOLUTION: To obtain this macromolecular actuator 1, a metal electrode is formed on the surface of an ion exchange resin formation or inside it, by repeating the processes of causing the ion exchange resin formation to adsorb a metal complex in an aqueous solution and reducing the metal complex with a reducing agent, and performing cleaning with a washing after depositing metal on the surface. As the result, the contact area of the ion exchange resin formation with the metal electrode increases, and the active sites of the electrode increase, and ions which transfer to the electrode increase also. And if a potential difference is produced between the surfaces of the ion exchange resin formation in a mutually insulated state, 1 ions 6 move to the cathode side, and water molecules transfer in the films and the quantity of water on the anode side differs from that on the cathode side, so the ion exchange resin formation bends. Consequently, it becomes possible to obtain a macromolecular actuator quick in response and large in displacement.

Further, a means E adds the basic current value to the correcting current value so as to obtain a basic drive current value. Meanwhile a means F compares the basic drive current value with a present predetermined current value. As a result, if the basic drive current value is less than the predetermined current value, a means G increases the degree of correction for the correcting current value in the basic drive current value so as to obtain an actual drive current value. Thereafter, a means H drives a motor I in accordance with the actual drive current value, thereby it is possible to give a steering assist torque to the steering system.
